Determination of Zinc by Acridine

Shigeo Wakamatsu


Abstract:

A new gravimetric method for the determination of zinc in iron, steel, iron ores and aluminum alloys has been developed. As the reagent, acridine and ammonium sulphocyanide were used to precipitate zinc in the presence of iron (II), nickel,aluminium, chromium, vanadium (IV), manganese,calcium and magnesium. The precipitate was ignited at 950°. By varying the procedure slightly, cobalt and molybdenum could be also determined. The described procedure offers a rapid, accurate method for analyzing zinc in metal and ore.
